Large sucrose shocks produce a free-energy barrier to
osmoprotectant accumulation during the initial recovery rate. Researchers
estimate this maximum energy, DGmax, for potassium pumping
using the known external, ~8 mM, and internal, ~250 mM,
concentrations of potassium for cells grown to exponential phase
in LB [primary sources]. |
